Acetal and ketal phosphites



United States Patent The present invention relates to novel acetals and ketals.

In the preparation of esters of polyhydric alcohols with acids of phosphorus such as phosphor-us acid or phosphoric acid there is a tendency to form polymeric ma- 7 terials as shown for example in Sander Patent 2,978,478 and Pierce Patent 3,005,007. Thus in the latter patent in Example 1 the product contained only 14.8% whereas the theoretical phosphorus content of the monomeric phosphate is 22.8%.

It is an object of the present invention to develop a method for preparing monomeric phosphites of polyhy- :dric alcohols having at least three hydroxyl groups. Such phosphites are convertable to the corresponding phosphates by conventional oxidative procedures.

Another object is to prepare novel heterocyclic acetal and ketal phosphites.

A further object is to prepare novel open chain acetal and ketal phosphites.

Still further objects and the entire scope of applicability of the present invention wil become apparent from the detailed description given hereinafter; it should be understood, however, that the detailed description and specific example, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed descritpion.

It has now been found that these objects can be attained by preparing novel acetals and ketals having one of the formulae In the above formulae R is alkyl, including cycloalkyl, alkenyl, aryl or haloaryl, R is alkyl, aryl, haloaryl or nitroaryl, R is hydrogen, alkyl, aryl, thaloaryl or nitroaryl, or R -C-R is an .alicyclic, i.e. a cycloalkyl, group, R is hydrogen, alkyl or aryl, R is hydrogen or alkyl, R is hydrogen or alkyl, R is hydrogen, methyl or ethyl, v is 0 or an integer, e.g., from 1 to 100, n is an integer between 1 and 10, m is 1 or 2, l is an integer of at least 4, e.g. 4 to 20, z is zero, 1 or 2 and y is 3.

Also there can be prepared compounds having the formula Rn Rt Rt 3,096,345. Patented July 2, 1963 ice where R is as defined above, R is as defined above and x is an integer of at least 1, e.g. from 1 to 100.

There are also embraced within the present invention the phosphite esters of diacetals and ketals of hexitols such as sorbitol and mannitol. Typical of such materials are compounds having the formula:

where R, R and R are as defined above.

In Formula V no attempt has been made to show the position of the hydrogen atoms on the asymmetric carbon atoms. The position of the acetal and ketal groups also can be varied so long as there are two such groups in the molecule.

The compounds of the present invention are useful as stabilizers for halogen containing vinyl resins, e.g. polyvinyl chloride and copolymers of vinyl chloride with minor amount of other materials such as vinyl acetate, acrylonitrile, etc. They also are useful as antioxidants for materials such as polyproylene.

A particularly important use for the acetals and ketals of the present invention is to hydrolyze them to give hydroxyl containing phosphites. Thus a compound having the formula:

When hydrolyzed with aqueous acid gives a secondary phosphite having the formula The byproducts are phenol and the aldehyde or ketone having the formula The symbols have the same definitions as previously set forth. This provides a simple and effective way of forming such monomeric phosphites containing a plurality of alcoholic groups without any danger of premature polymerization. The hydrolyzed phosphites are useful for preparing polyurethanes by reaction with organic isocyanates, e.g., toluene diisocyanate. The polyurethanes can be foamed or elastomeric.

Phosphates corresponding to the hydrolyzed phosphites can be prepared if prior to the acid hydrolysis of the acetal or ketal it is oxidized with alkaline hydrogen peroxide. These phosphates have numerous uses as shown in Gilbert Patent 2,789,124, for example. They can also be reacted with organic polyisocyanates to form foamed or elastomeric polyurethanes.

The novel compounds of the present invention are prepared by reacting a phosphite of the formula (RO) P with an acetal or ketal having one of the formulae HO-CH:

VIII

potassium phenolate, potassium octylate, lithium, ethylate, sodium salt of 2-1nethyl-2-ethyl-4-hydroxymethyl dioxolane, potassium'salt of 2,2-dimethyl-4-hydroxymethyl dioxolane as well as the alkali metal salts of the other acetals of Formulae VI through X. The alkaline catalyst usually will have a pH of at least 11 in a 0.1 N 80- lution. The phenol or monohydric alcohol formed in the reaction is preferably removed by distillation, usually at reduced pressure, e.g., 5-20 mm. a

In place of the alkaline catalyst there can be used 0.1-

10% of a secondary phosphite, e.g. diphenyl phosphite,

dicresyl phosphite, didecyl phosphite or dimethyl phosphite.

In making the compounds of Formula I When 1 is zero there should be employed at least 3 mols of the starting acetal or ketal of Formula VI per mol of the starting phosphite, e.g., triaryl phosphite, used. Preferably an excess, e.g., a 20% excess of the acetal or ketal is employed. In preparing compounds of Formula I when z is l there are used 2 mols of the starting acetal or ketal per mol of starting phosphite. In preparing compounds of Formula I when z is 2 there is used 1 mol of the starting acetal or ketal per mol of starting phosphite.

In preparing compounds of Formula II (or V) there is used 1 mol of the starting acetal or ketal of Formula VII (or X) per mol of the starting phosphite, e.g. a triaryl phosphite.

In preparing the Compounds of Formulae III and IV there is used 11 mol of the acetal or ketal of Formulae VIII or IX for each 2 mols of the starting phosphite.

As starting phosphites there can be used triphenyl phosphite, tri o-cresyl phosphite, tri p-cresyl phosphite, tri m-cresyl phosphite, tri xylenyl phosphite, tri p-butylphenyl phosphite, tri ot-naphthyl phosphite, bis phenyl decyl phosphite, phenyl bis decyl phosphite, tris decyl phosphite trimethyl phosphite, triethyl phosphite, tri octadecyl phosphite, tris cyclohexyl phosphite, tri oleyl phosphite, triallyl phosphite, tri o-chlorophenyl phosphite, dibutyl phenyl phosphite, tri p-chlorophenyl phosphite, tri m-chlorophenyl phosphite, tri bromophenyl phosphite, trilauryl phosphite, tri B-naphthyl phosphite.

To make the starting acetals or ketals of Formula VI there are reacted a polyhydric alcohol having three hydroxyl groups such as glycerine, 1,2,6-hexanetriol, trimethylolethane, trimethylolpropane, trimethylolbutane, trimethylol phenyl methane, trimethylol butylphenyl methane, 1,2,4-butanetriol, 1,2,3-butanetriol, 1,2,3-penta-netriol, 2-methyl-1,2,3-butanetriol with an aldehyde or ketone such as formaldehyde, acetaldehyde, propionaldehyde, butyr-aldehyde, isobutyraldehyde, valeraldehyde, lauraldehyde, steal-aldehyde, isovalaraldehyde, heptaldehyde, benzaldehyde, acrolein, crotonaldehyde, oleic aldehyde, o-tolulaldehyde, p-tolualdehyde, a-naphthaldehyde, B-naphthaldehyde, p-chlorobenzaledehyde, o-chlorobenzaldehyde, o-nitrobenzaldehyde, p-nitrobenzaldehyde, 2,4- dichloro benzaldehyde, m-bromo benzaldehyde, m-nitrobenzaldehyde, m-chlorobenzaldehyde, hexahydrobenzaldehyde, acetone, methyl ethyl ketone, methyl-n-propyl ketone, diethyl ketone, hexanone-Z, hexanone-3, methyl t-butyl ketone, di n-propyl ketone, diisopropyl ketone, diisobutyl ketone, di n-amyl ketone, stearanone, cyclohexanone, cyclopentonone, benzophenone, acetophenone, propiophenone, methyl cyclohexanone, cycloheptanone, cyclooctanone. The reaction between the trihydric alcohol and aldehyde or ketone is carried out under anhydrous conditions in the presence of a small amount, e.g., 0.1- 5% of an acid such as hydrochloric acid or p-toluene sulfonic acid based on the amount of alcohol reactant. Many of the starting acetals and ketals are old as shown in Gilbert Patent 2,789,124 and Hoplf Patent 2,095,814. The other starting acetals and ketals can be prepared by conventional procedures such as those of the Gilbert and Hopff patents. The starting acetals and ketals of F ormula VI which have at least one l a (OHQCHO) group can be prepared in the manner of Hoplf by adding an alkylene oxide such as ethylene oxide, propylene oxide or butylene oxide to the acetal or ketal of a trihydric alcohol and an aldehyde or ketone. The greater the number of mols of alkylene oxide used per mol of acetal or ketal the greater the number of GHZJJHO groups in the product. 7 Examples of starting acetals or ketals Within Formula V-I include 2-methyl-2-ethyl-4-hydroxymethyl dioxolane, (2-methyl-2-ethyl-4-methyloll ,3 -dioxacyclopentane 2,5-dime-thyl-2-ethyl-S-hydroxymethyl m-dioxane, 2,5 -dimethyl-2-ethyl-5 -methylol- 1 ,3-dioxacyclohexane 2,2,5-trimethyl-5-hydroxymethyl m-dioxane, 2,2-dimethyl-4-hydroxymethyl dioxolane, 4-hydroxymethyl dioxolane, 2-methyl 4-hydroxymethyl dioxolane, Z-ethyl 4-hydroxymethyl dioxolane, 2-propyl 4-hydroxymethyl dioxolane, 2-isopropyl-4-hydroxymethyl dioxolane, 2-undecyl-4-hydroxymethyl dioxolane, 2-heptadecyl-4-hydroxyrnethyl dioxolane,

Example 14 Phenyl diethylidene sorbitol phosphite was prepared by heating 0.1 mol (18.2 grams) of 1,3,2,4-diethylidene sorbitol [prepared by the method of Hockett et al., J.A.C.S.,

18 vol. 69, pages 849-851 (1947)], 0.1 mol (31.0 grams) of triphenyl phosphite and 0.1 gram of sodium methylate to 150 C. A slight vacuum was applied and phenol was removed by distillation while the temperature was slowly raised to 180 C. After removing nearly the theoretical amount of phenol (0.2 mol), the vacuum was reduced to 1.0 mm. Hg to remove the final traces of phenol. The 5,6-rnonophenyl phosphite ester of 1,3,2,4-diisopropylidene sorbitol product was a white solid obtained in a 94.3% yield.

Example 15 1.0 mol (118.2 grams) of 1,6-hexanediol, 0.5 mol (36.0 grams) of methyl ethyl ketone, 150 grams of hexane and 2 grams of p-toluene sulfonic acid were heated and refluxed through a fractionating column fitted with a water trap to remove the water of reaction. After 20 hours of refluxing, the theoretical amount of water (9 grams) was collected. The reaction mixture was neutralized with dry sodium carbonate and filtered. The solvent was removed in vacuo leaving 141 grams of 2,2-di-(6hydroxyhexoxy) butane, an amber solid having a hydroxyl number of 379 (theory is 386).

To 0.1 mol (29.0 grams) of the 2,2-di-(6'-hydroxyhexoxy) butane there were added 0.2 mol (62.0 grams) of triphenyl phosphite and 0.1 gram of sodium methylate, and the mixture was heated to 150 C. A slight vacuum was applied and phenol was removed by distillation while the temperature was slowly raised to 180 C. After removing 18 grams of phenol, the vacuum was reduced to 1.0 mm. Hg and an additional 1.5 grams of phenol dis tilled. The total amount of phenol (19.5 grams) removed corresponded closely to theory (18.82 grams). The product was cooled to C. and filtered. The 2,2-bis-(diphenoxyphosphaoxyhexoxy) butane product was obtained as a viscous, amber liquid in an amount of 68.9 grams (95.5

Example 16 One mol of pentaerythritol and one mol of methyl ethyl ketone, grams of hexane and 2 grams of p-toluene sulfonic acid were heated and refluxed in the manner described in Example 15 to remove the theoretical amount of Water (18 grams). The product was neutralized with dry sodium canbonate and filtered. The solvent was removed in vacuo to obtain Z-methyI-Z-ethyl- 5,5-bis-hy.droxymethyl-1,3-dioxacyclohexane.

To 0.1 mol of the 2-methyl-2-ethyl-5,S-bis-hydroxymethyl-1,3-dioxacycl0hexane there were added 0.1 mol (31.0 grams) of triphenyl phosphite, and 0.1 gram of sodium methylate and the mixture heated in the manner of Example 15 to remove the theoretical amount of phenol (18.8 grams). The product was 2(phenoxy)-9-methyl- 9-ethyl-1,3,8,10-tetraoxa-Z-phosphaspiro- (5,5) undecane.
